The first part of the chapter examines the wave and tidal stream sector, providing an overview of the wave and tidal resource both within the UK and globally, and provides details of the various classifications of wave and tidal energy device types. An outline of the current status of ocean energy array progress, and the development of future array projects, provides details of the technology challenges the sector faces. Details of the levelized costs of energy for wave and tidal energy, the need and potential for cost reduction within the sector, information regarding the uncertainty of cost within the sector, and an overview of the potential of cost of energy reduction through innovation are explored in detail. The second part of the chapter reviews the installed capacity, technology, and operation of hydropower, together with the prospects for its further development and possible social and environmental constraints on that development.

Keywords:   ocean energy, wave energy, tidal energy, marine energy, hydropower
